This is a plug-in harness that provides a single 12v output circuit (power and ground) from your factory tail light harness. With it's quick simple installation there is no need to splice or t-tap into your factory tail light harness and damage the wires. This is a great way to add a clean sealed circuit for your license plate light or other low current light or accessory. It is made with factory connectors that plug directly into your Polaris wiring harness and also has a sealed connection at the output harness so your entire wiring harness remains sealed from dust, dirt, mud and water.
